Abstract

A method and apparatus for washing impurities such as phosphine, ammonia, hydrogen sulphide and/or arsine out of crude gases by means of sulphuric acid in at least one washing column is described. To overcome the disadvantages of known processes, such as formation of by-products which cause blockages and high equipment cost, it is proposed to circulate dilute sulphuric acid in an (n-2)th washing stage, n being greater than or equal to 3, and to circulate concentrated sulphuric acid in an (n-1)th washing stage, and to charge fresh concentrated sulphuric acid in an (n-1)th washing stage at the top of the washing column. A 3-stage process here represents a particularly economical solution. <IMAGE>
